TIKA
A kaolin plastic enough to throw and work wet · White-firing, and a source of alumina and silica · Goes into porcelain and white stoneware bodies, and into glazes as a suspender · Higher in potassium than most ceramic kaolins, so the less refractory of them

Tile #6 is a kaolin, and unusually for one it is plastic — it can be thrown and worked wet where a kaolin is normally short. It fires white and supplies alumina and silica to a body or a glaze.
Tile #6 is a kaolin, and unusually for one it is plastic. It takes and holds a shape well enough to throw with, and it dries with real strength in the greenware, which is why it goes into porcelain and white stoneware bodies — the whiteness of a kaolin without the shortness that normally comes with it. In a glaze it supplies alumina and silica and keeps the slurry in suspension. It carries more potassium than most ceramic kaolins, so it begins to soften earlier in a firing than a low-alkali kaolin does. A kaolin has no cone rating of its own; what matures is the body it goes into.
